128K Analog Recap photos and WTB:128K Motherboard

If you are going for real authenticity, the 128k-Plus didn't use the pins, they used double-sided, crazily strong foam tape (of which I have a reel).

On a Gemini-upgraded MacPlus, they used hot glue sandwiched between the ripped foam tape.

my 128k has all the 128k internals, but has a 512k back case. i figure it got swapped with an actual 512k at a dealer while in for service.

i bought it around 1990 and added Plus ROMs and a MacRescue daughterboard with 6 MB (4MB RAM like a Plus, 2MB RAM Disk).

amazingly enough, about a month ago i bought what was advertised as a 128k. when i opened it up i found it was really a 512Ke LB inside a 128k case. so i put the LB's in their respective cases.

maybe it's the Mac my 128k got all mixed up with and now they're reunited after 35 years?

I have seen red battery holders in late AB units also, probably several suppliers for a same part. The early AB boards had a small top metal stiffener serving as a cooling device also, and the cardboard shield was brown instead of white IIRC

Sorry to be waking up an old thread. I found this site while looking for value information and signed up because I actually know the answer since I myself made that change. The red battery holders were simply a quick fix so that service people could know whether the unit had a standard 110v AB or the "universal" 110-220v version of the AB without cracking the case open. It was early days for bar codes and they did not include much detail about the internals. The problem occurred while I was in Taiwan visiting Capetronic (one of 3 suppliers of the AB) and their plastic molder was very nearby so we went over and asked if they had any raw material (nylon 6/6 IIRC) in a different color. They did and it happened to be red so they immediately switched that press over and ran several thousand red ones. On returning to Cupertino after finishing my other visits to Korea and Japan I found that air freighted ABs had beat me back and there was a bit of drama about me (the purchasing guy) having made an -engineering- decision. I won, and actually got manufacturing engineer added to my job description by Steve. I'm not sure just how long they were used but it could not have been before about March of 84. FWIW, we had 3 sources for the AB -Capetronic (owned at the time by BSR), Samsung and an in-house line in the Warm Springs factory. I believe most came from Samsung, who also supplied about half of the 9" CRTs, with Clinton-Taiwan supplying the other half. Good times!

That's a cool story, @Huguenot! Thanks for posting it.

That's helpful. Do you have any other stories from that period? Glad you joined to forum!!

I do have a few more stories, it was a crazy time. I posted one on folklore.org years ago about the rubber feet under the case and have written a few since, but Folklore seems to have been absorbed by the Computer History Museum in Mt. View and can't be added to any more. I was one of the 2 purchasing agents on the project in the early days, responsible for "everything that is not soldered to the logic board". That included the logic board PCB, AB, casework, cables, keyboard, mouse and a lot of the factory equipment too while it was being built. My personal "Golden Mac"(Identical to Chris Espinoza's in the pic a few posts above) carries s/n F347109. These were handed to us each personally by Steve during an event at Bandley 3 the week of the product launch and I believe there were only 100 in total. Is this the right sub-forum for stories like this or would another be more appropriate?
